BSU Shaders FAQ
10 questions players actually ask, answered.
How do I turn on BSU Shaders after installing it?
Open Options > Video Settings > Shaders, then locate and select BSU Shaders from your shader pack list. Click Apply and the shader will load on your next world.
Why does my world look washed out or too bright?
Check your Lighting Intensity setting in the shader options—it may be set too high for your preference. Adjust it downward and reapply to find a balance that suits your monitor and playstyle.
Can I use BSU Shaders with other mods like Optifine or Sodium?
BSU Shaders works with Iris (the shader loader for Sodium), but compatibility with Optifine varies depending on your setup. For best results, use Iris + Sodium as your rendering foundation.
My FPS dropped a lot after enabling BSU. How do I fix this?
Lower your render distance, disable or reduce shadow quality in the shader settings, and ensure your GPU drivers are up to date. You can also reduce Color Saturation slightly to ease GPU load while keeping the fantasy aesthetic.
Why do caves look too dark even with the shader on?
BSU respects low light levels to maintain atmosphere, but you can enhance cave visibility by adjusting the Lighting Intensity or enabling any ambient light options in the shader menu to brighten shadowed areas.
How do I make underwater look better with this shader?
BSU includes underwater enhancements by default, but you can fine-tune them through the shader settings—look for water fog, caustic, or underwater lighting options to customize the appearance to your liking.
Do different biomes look too similar or have weird lighting?
BSU applies consistent lighting rules across biomes, but you can adjust Color Saturation to make biome colors pop more distinctly, or tweak individual lighting settings to create more contrast between environments.
Is BSU Shaders safe to use in survival worlds?
Yes, shaders are purely visual and do not affect gameplay, world data, or multiplayer compatibility. You can enable or disable BSU at any time without impacting your save file.
Why do shadows look strange or flicker?
This often happens when shadow distance is too high for your hardware or when Complementary Unbound's shadow settings conflict with your world setup. Try reducing shadow quality or distance in the shader options.
Can I use BSU Shaders on a server?
Shaders are client-side only, so you can use BSU on any server without needing to install it server-side. Other players won't see your shader effects, only you will.
